Description

Domestic solar and methane energy utilize system
Technical field
The utility model relates to helioplant, refers in particular to a kind of domestic solar and methane energy and utilizes system.
Background technology
Energy problem is one of significant problem of the world today.The energy is the important substance guarantee of economy and social development, and simultaneously energy resource consumption can have an immense impact on to environment again.China is a production of energy and consumption big country.Because China is populous, energy utilization rate is low, in recent years, and consuming excessively of conventional energy resource and becoming increasingly conspicuous so that the Energy situation of China is more and more severeer of problem of environmental pollution.In conjunction with the energy resource structure characteristics of China and the encouragement of national policy etc., increasing is to research and the investment of regenerative resource, solve current energy consumption problem, has far reaching significance to alleviating China energy problem, particularly future diversified take regenerative resource in the energy resource structure on basis, fully utilize two classes or a few class energy, the various energy are replenished mutually, bring into play its advantage separately to improve its efficiency of energy utilization, just seem extremely important.
The annual solar radiation total amount that receives of China's land surface is equivalent to 2.4 * l04, hundred million t standard coals between 3.3 * l03~8.4 * l06kj/ (m2.a), belong to one of abundant country of solar energy resources; And China is a large agricultural country, and the agricultural wastes resource distribution is extensive, and wherein the agricultural stalk annual production surpasses 600,000,000 tons, can be used as approximately 3.5 hundred million tons of the stalks that the energy uses, and approximately amounts to 1.5 hundred million tons of standard coals.Industrial wastewater and livestock culture field waste can produce nearly 800 billion cubic meters of biogas in theory, are equivalent to 5,700 ten thousand tons of standard coals.Therefore China's solar energy and biomass energy-methane energy aboundresources as combining mutually of two kinds of rational energy replenished, can solve the energy-consuming problem in the vast rural area of China substantially.
At solar energy and methane energy in conjunction with aspect utilizing, also there is research in China, it the most typically is exactly solar-energy methane pit, it is the solar water that will be stored among the thermal storage water tank, enter biogas generating pit bottom heat exchange coil by downcomer, carry out exchange heat with the fermentation raw material in the fermentation vat, thereby improve the biogas generating pit fermentation temperature.Hot water is through after the heat exchange coil heat exchange, and drop in temperature is pumped into solar collector by circulation pipe by hot water circuit again, draw solar thermal energy, enter the hot water water storage tank, so constantly circulation, utilize solar energy, improve biogas generating pit winter, spring fermentation temperature, thereby improve factor of created gas.In fact it is exactly a solar water heater.Utilize the hot water circuit of solar energy that biogas generating pit is heated up.Mainly there is the defective of 3 aspects in it:
1, not energy-conservation, intensification effect to biogas generating pit is also undesirable, because what use in the most of China area is vacuum pipe solar water heater, it is to come heating water by the heat that absorbs sunlight, in summer, the very sufficient water temperature of sunlight is high, and the temperature of biogas generating pit is not low yet, and the needed hot water amount of family is also little, real biogas generating pit temperature is low, the spring that hot water amount's demand is larger, autumn, three season of winter, water heater will rely on long electric auxiliary heating fully, and we are that evening is many with hot water generally, that is to say, be finished that the courage the inside has been exactly cold water after the hot water evening, and do not have the sun evening, electric heating will start so, the solar energy water courage is not totally enclosed, can be by spells by electric heating, insulation, the solar energy utilization is very low, and is therefore not energy-conservation.And its installation is complicated, such as Rig up error, can affect the city look and feel in outward appearance, quality and the city of house, troublesome maintenance.
2, function singleness, energy storage is limited, solar energy utilization ratio is low, the solar energy utilization comprises that solar energy heat utilization and solar photoelectric utilize two parts, and this only utilizes the thermogenetic hot water circuit of a small amount of light to be used for the intensification of biogas generating pit, do not have device of solar generating, can not solve the electrical problem (such as household electrical appliance such as domestic lighting, TV, computers) of family, function singleness.When sunny, only depend on when heat energy is many to keep the temperature of water in the boiler casing to carry out thermal energy storage.And boiler has air vent hole, can cause energy loss, and can not effectively store energy, as meets and overcast and rainyly not can play a role.
3, there is not heat abstractor, the temperature of silicon solar battery assembly can make photoelectric conversion efficiency descend, impact generating effect, every rising 10 degree of temperature, its open circuit voltage descends 0.3%, and the 50 degree open circuit voltage decline 15mV(that raise are 14%), it does not all arrange the heat radiation facility in design and use, pure in natural heat dissipation, greatly affect power benefit and cell panel life-span.
Summary of the invention
The purpose of this utility model is for the defective that exists in the background technology and problem improvement and bring new ideas in addition, providing a kind of converts solar energy into electrical energy and the two combines with methane energy, improve solar energy and methane energy utilization ratio, domestic solar and the methane energy that is applied to home energy source that complement each other utilizes system.
The technical solution of the utility model is that a kind of solar energy and methane energy of solar-energy photo-voltaic cell system, cooling system and inversion switching control system of comprising of structure utilizes system, wherein:
